In .orderthat this invention may be better understood I will refer: to parts of my former m'achineas disclosed in the patent aforesaid but will not give a detailed descriptionof such parts as they are fully disclosed and described in the former'patent.

The stooker frame, indicated generally by the reference letter E, supports rotatably the inner end of thebasket shaft 11 provided intermediate of its ends with a curvilinear portion 12. adapted to carry. thebasket collector F. The inner side of the" basket frame is suitably supported from the frame offtheibinder, (not shown) such being. omittedYin the presentdisclosure and thexouter side issupported by a ground wheel 14 rotatably mounted on the outer end of. the shaft 11. A crank member 15 is fixed to the shaft 11 and carries an angular lever 16 pivotally mounted thereon, the inner end of which is substantially curvilinear as-shown at 17. and is adapted to engage with'a pin 18', thereby limitingathe outer motion of the lever which is adaptedkto be pressed inwardly to engage with the spokes of the wheel 14.

The lever 16' is provided witha projection 27 designed to be engaged by a spring 28 adapted to holdthe said lever normally disengaged fromthespokes of the wheel and the said lever is adapted tobe moved into engagement with the spokes through themedium of the bell crank 29 pivotallymounted on the frame E and operatively connected by the link 30 with the bell crank 31 mountnow described in detail.

ed on the frame. A flexible member, such as a cable 32, is connected to the bell crank 31 and passes to a convenient location adjasame manner as disclosed in my former patent and is caused to be'withdrawn and as it forms no part of the present invention is not further described.

The above parts form no part of the present invention which comprises in reality pressure arms carried by the basket and steadying fingers carried by the frame and associated with the basket. These parts are .are fitted with outwardly extending cranks a and b and the rear end of the shaft 1) is supplied with a single arm (1 which is permanently secured to the shaft and is held normally open in respect to the basket by means of a coiled spring (1 mounted on the shaft and having one end fastened to thebasket as indicated at d" and the other end projecting and coiled around the arm as indicated at d. .The rear end of the shaft a is supplied with a U-shaped arm 6 which is permanently secured to the shaft and is held normally in the open position in respect to the basket by means of acoiled spring 6 mounted on the shaft and having one end fastened to the basket as indicated at e" and the other end extending and looped around the arm as indicated at 6 These springs normally hold the arms in the upper position so that they do not'interfere with the passing of the sheaves, into the basket from above.

' In order to close the arms when the basket is dumped by the turning of the shaft 11 I provide a pair of striker plates 7' and g which are permanently secured to the shocker frame in a location in advance of the shaft 11 and provided each with adown of the basket the cranks a and b will strike the plates f and 9 (see Figs. 1 and 8) and in the initial turning movement of the basket will be caused to rotate in the direction indicated by the applied arrow Fig. 8 thereby causing the rods a and b to turn in a direction such that the arms 03 and e will be both swung inwardly over the sheaves contained in the basket. "This action causes the sheaves to be compressed and held tightly within the basket during the dumping action and here it will be observed that as the basket continues to turn the outer ends of the'crankride over the guides and hold the arms closed until the cranks escape over the ends'of the guides, which action occurs just prior to the basket being upended. The instant the cranks free the guides the rods are freed and the springs d and c operate to swing the arms back to their original open position.

After the basket has dumped and has been returned to the initial receiving position the cranks are lying on the top side of the plates f and g and are ready for further action. In order to steady the stook after it has left the basket I provide steadying fingers which are automatically controlled to pass in, in front of the stook and remain with it as the shocker advances, the fingers actually being timed to pass backwardly at the same speed the grain stooker advances so that their movement in respect to the ground is relatively zero.

These fingers have herein been shown as positioned at the outer side of the basket but in this connection I wish it to be understood that they could be applied at both sides of the basket if occasion demand.

The inner beam E'at the outer side of the'shocking machineis fitted with abearing E which receives afsleeve' h mounted on the shaft 11 and on the sleeve I mount V chains 0 and 0' with the chain wheels 7'.

and k. I

From this arrangement it will be seen that when the shaft 11 turns the chain 0 rotates the chain 0. arranged inthe manner shown to allow of varyingthe speed at which the inner chain wheel travels. this being readilv accom plished by varying the size of the chain wheel]; which drives the chain wheel 7'. The chain 0 is fitted with two special links indicated at p and p, such special links be The chain wheels are a ing provided with opposing lugs '79" which form bearings for pivot PHIS q located at the ends vof the steadying fingers r and 8.

These steadying fingers are sufficiently long so that when extended crosswise of. the

basket they pass practically across the same and they' are arched slightly from'end'to end so as to pass around the front of the stook when the fingers are in use.

Further the 'speci 1 links carrying the fingers are introduced in the chain at opposite ends thereof'so that when onefinger is ahead the other is back; Each finger is controlled in a manner shortly to be described so that when going back orrearwardly it takes a horizontal position as best shown in Fig. 1 of the drawings and when "going ahead or forwardly it-is swung up into the vertical position. In going back it stays with "the stook for ashort interval.

after it is dumped steadying it and then swings up to the vertical position and is reset so that it will subsequently pass inbehind a further stook when the same is dumped. y H I On the fingers and in allocation-adjoining the pins I mount rollerst and t which rollers are adapted to ride-continuously on "a track which controls the movement of-the fingers. The track'is formed from two bars '0 and w permanently secured to 'theIf-rame beam 'E and arranged so that the rollers are guided first by the 'one plate-and then by the other. The upper plate has 'the ends thereof curving "gradually inwardly as indicated at o and c and is provided with a right angled flange o", the edge of which gradually vanishes at" "the endsinto the curved ends *0" and a *1).

" The platew is supplied with a right angled flange '10 which pas'sesthe'full length of the plate-and is concentric at the ends to theshafts 1 1 and-J. "The curved ends of the plate upass within-the curvedfiange bearing ends of the plate w and the dis;

tance between the two plates at }the ends is slightly greater'than the diameterof the rollers which'a-llows the rollersto' pass tween them. f

The arran-gement'of the plates inrespect to the pivot pinsand rollers is such "that when the rollers are riding J on "the flange w the arms are maintained in a horizontal position. This will be best apparent by refe'rring'to Figs. -'3 and 15 whereit will be seen that the lower roller is v-rid1ng 'on the flange and the finger ,eXtendinghorizontally.

As this roller passes from the flangejo'f the plate w to the end 0 of the plate '0 theroller is graduallyswungiby the plate 1) from the horizontal position to' an "inclined position, it being in theincline'd -po sition' '(see Fig. 6') when ridingon the flange e As it-passes alongthe flange-'0" the roller-is maintained in'the inclined position' until it rides back on to the end 0 l of the plate where it isagain brought to the vertical position and goes back on to :the flange 10" of the lower plate. Inconsidering this action it will beunde'rst'ood that the' chain ismoving in the direction-indicated by the applied arrow '3 and is being driven bythe shaft 11.

. l l n placing the fin ers on the chains it is necessary to locate t e s ecial links vcar-rying them so that when t e basket is in the sheafrece'iving .or normal position the fingers will stop operating for the reason. that the shaft "11 isthrown out of commission each time the basket dumps;

. In the initial movement of the fingers the=finger s will be swung down in advance of the upturning end of the bas'ket andin advance of the stook-and in passin backwardl will stay with the stook stea' ying it until 1t reaches the position occupied by the finger-v in Fig. 1 oft-he drawings.

In this position it'will stop as the parts are designed so that when the basket is dumped andreturned' to the initial position the finger s will have reached the position as shownloccupied bythe finger win Fig. 1 of the-drawings.

During the movement of the fingers as above: disclosed 'the 1 finger m travels like distance first being "turned fromithe horizontal position a as shown j-in Fig. -1 to the inclinedpositionand then traveling forwardly in the inclined position untilit takes :the -position previously occupied' b'y the finger s.

this arrangement there is oneor other of t 'e fing'ersat all times ready to passi-n ahead :of the stock each time the basket is dumped and go back-withit and steady it on the ground.

-In the 'above disclosure it will be easily understood that thedetails of the track could be readilymodified without in l the least departingirom the spirit of this part of'the invention which "resides in providing fingers which canpass backwith the Stock and steadyit and arranged so' that they'can be controlled throughout-theirentire movemerits. r
